(Cl. S11- 11) 3 Claims. 1

This invention relates/,to ychiropractic tablesl of the type having.azfootrestgand: a platform` atuone end, andinrparticulariaftoggleiattachment' for automatically' elevating the footrest offra ,chiropractic tableas, the table is lowered to a positionbeen lowered and this ,islobjectionablebecauseY the patient isinconvenienced thereby. Withlthis thought. in4 mind thisinventioncontemplates pairs of hinged levers connected=ato the ends of"the f chiropractic table and to the-platform' mounting of the tablewhereby the outward movement of the platform, as the table is loweredelevates the inner ends of the levers whereby with the inner ends of thelevers connected to the foot rest the foot rest is automaticallyelevated.

The object of this invention is, therefore, to provide means forconstructing an attachment for chiropractic tables whereby the elementsmay readily be installed on the table and connected to the foot rest sothat the outward movement of the platform raises the foot rest.

Another object of the invention is to provide an attachment forchiropractic tables by which the foot rest is elevated as the table islowered that may be installed on tables now in use.

A further object of the invention is to provide a foot rest elevatingattachment for chiropractic tables which is of a simple and economicalconstruction.

With these and other objects and advantages in view the inventionembodies a yoke mounted under the foot rest of a chiropractic table withtoggle action levers pivotally connected to a standard at the end of thetable and also to an outwardly moving platform of the table whereby withthe levers connected to the yoke of the foot rest the foot rest iselevated as the platform moves outwardly.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings wherein:

Figure 1 is a vertical longitudinal section taken on line I-I of Figure2 through the end of a chiropractic table showing the attachmentinstalled thereon.

Figure 2 is a plan View of the end of the table ..tratng' the positionof -thev attachment fon: the wtable.

Figure 3 is a side elevational viewof theattachment with;` parts shownlin section showing the r foot rest in the ,lowerl position.

Figure 4 is a cross sectionthrough the. endzof 1 the .tabla showing-thefootfresttwithfthe yoke of .the-.attachment extended downwardlytherefromandztaken on.line4-.-4 of Figure 1.

Referring nowto the drawingsr whereins like reference charactersfdenotecorresponding,` parts :the ,foot `resttoggleattachmentzof :this:invention includesayoke :Ii' for attachingfan outer pair. of ,l5

The ends '26 and 2 of the yokes I6 are attached to the hubs 28 and 29 ofthe platform I3 by set screws 30 and 3|, respectively, and the outerbase of the yoke is provided with extensions 32 and 33 through which theends of the bars and I2 are pivotally connected to the yoke by a rod 34.

The opposite ends of the bars and I2 are pivotally connected to the bars23 and 2| through a rod 35 and, as illustrated in Figure 1 the rod 35 ispositioned to register with the slots 36 in vertically disposed bars 3land 38 that are pivotally connected to downwardly extended ends of theyoke I4 by a rod 39.

The opposite ends of the bars 20 and 2| are pivotally connected throughthe clamps I8 and I9 to a rod 4U and the clamps are secured on thestandard 22 by bolts 4| and 42.

The standard 22 is carried by the outer ends of the arms 23 which aresupported in webs 43 of the bars 24 and 25 and the foot rest II isprovided with downwardly extended rods 44 and 45 that are slidably heldin cylindrical sockets 46 and 41 on the outer ends of the rods 24 and25. The hubs 28 and 29 and the platform I3 are carried by rods 43 and 49that extend through the bars 24 and 25.

With the parts arranged in this manner the toggle bars extenddownwardly, as illustrated in Figure 3 when the chiropractic table isupright and when the table is lowered to the position in whichadjustments are made the bars 20 and 2| and Il and I2 move-the foot restI'I upwardly through the rod 35 which is positioned in the 3 notches 36.The upward movement of the foot rest is adjusted by placing the rod 35in the different pairs of notches.

The attachment may readily be installed on chiropractic tables asdisclosed and it will be understood that the attaching elements at theends of the device may be modied to correspond with tables of differentdesigns.

It will also be understood that other modications may be made in thedesign and arrangement of the parts without departing from the spirit ofthe invention.

What is claimed is:

1. A chiropractic table attachment comprising two pairs of parallelbars, an intermediate rod pivotally connecting the inner ends of thesaid pairs of parallel bars, a pair of vertically disposed bars havingnotches in the edges thereof, means pivotally connecting the upper endsof the said vertically disposed bars to a foot rest of the table, meansconnecting the inner pair of parallel bars to the end of the table, andmeans connecting the outer pair of parallel bars to an outwardly movablepart of the table, said notches of the vertically disposed barspositioned to receive the said intermediate rod connecting the innerends of the parallel bars.

2. A chiropractic table attachment comprising two pairs of parallelbars, an intermediate rod pivotally connecting the inner ends of thesaid pairs of parallel bars, a pair of vertically disposed bars havingnotches in the edges thereof, a yoke having downwardly extending endsmounted on a foot rest of the table, a rod pivotally connecting theupper end of the said vertically disposed bars to the downwardlyextending ends of the yoke of the foot rest, means connecting the innerpair of parallel bars to the end of the table, and means connecting theouter pair of parallel bars to an outwardly movable part of the table,said notches of the vertically disposed bars positioned to receive thesaid intermediate rod connecting the inner ends of the parallel bars.

3. A chiropractic table attachment comprising two pairs of parallelbars, an intermediate rod pivotally connecting the inner ends of thesaid pairs of parallel bars, a pair of vertically disposed bars havingnotches in the edges thereof, a yoke having downwardly extending endsmounted on a foot rest of the table, a rod pivotally connecting theupper end of the said vertically disposed bars to the downwardlyextended ends of the yoke of the foot rest, U-shaped clamps positionedon a standard extended through the end of the table, a rod pivotallyconnecting the end of the inner pair of parallel bars to the saidU-shaped clamps, a yoke mounted on a platform carried by the table, anda rod pivotally connecting the ends of the outer pair of parallel barsto the yoke of the platform, said notches of the vertically disposedbars positioned to receive the said intermediate rod pivotallyconnecting the inner ends of the pairs of parallel bars.
